The first end includes first and second inlet ports, while the second end portion includes an outlet port. The flow-through valve further includes a valve cartridge including a first fixed disk having an opening thereon, a first moveable disk in fluid communication with the first fixed disk, a second fixed disk having an opening thereon and a second moveable disk in fluid communication with the second fixed disk. The fixed disks and moveable disks may be configured within the valve cartridge to independently adjust the hot/cold water flow or the temperature/flow rate.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a flow-through valve assembly for a faucet, and more particularly to a two-handled flow-through valve assembly alternately configurable to provide adjustment of the hot and cold water or the flow rate and temperature.

Various valves to control the flow of hot and cold water are known for residential applications such as kitchen or lavatory fixtures or bath/shower fixtures. Such conventional valves operate in one of two modes—a hot/cold water control mode or a temperature/flow rate mode. However, such valves are not readily configurable to operate in either mode. Accordingly, there is a need for a valve design which may be adapted to provide either control mode.

Conventional valves include a radial outlet or discharge from the valve body so water flows axially into and radially out from the valve. As such, conventional valves limit the shape of the faucet and the placement of the valve. Accordingly, there is a need for a flow-through valve design in which water flows axially into and out from the valve.

SUMMARY OF THE INVENTION

The present invention provides a flow-through valve including a valve housing having an outer cylindrical wall connecting first and second axially offset end portions to allow in-line fluid flow from the first end portion to the second end portion. The housing includes first and second inlet ports while the end portion includes an outlet port for discharging the fluid. In addition, the flow-through valve includes a valve cartridge having a first fixed disk disposed in the housing having an opening therethrough and a first moveable disk disposed in the housing and in fluid communication with the first fixed disk. The first moveable disk is rotatable within the valve housing and cooperates with the first fixed disk to selectively control fluid flow rate from the first inlet port to the outlet port. The first moveable disk includes a first actuating arm extending radially outwardly therefrom for selectively rotating the first moveable disk.

The valve cartridge further includes a second fixed disk disposed in the housing having an opening therethrough and a second moveable disk disposed in the housing and in fluid communication with the second fixed disk. The second moveable disk is rotatable within the valve housing and is operable to cooperate with the second fixed disk to selectively control fluid flow rate from the second inlet port to the outlet port. The second moveable disk further includes a second actuating arm extending radially outwardly therefrom for selectively rotating the second moveable disk.

In one configuration, the rotating disks are configured to provide a hot/cold control valve wherein manipulation of a first rotating disks adjusts the flow rate of hot water through the valve assembly and adjustment of the second rotating disks controls the flow rate of cold water through the valve assembly. The valve assembly is alternatively configurable so as to provide a flow/temperature valve control wherein manipulation of the first rotating disk controls the flow rate of water through the valve assembly and manipulation of the second rotating disk controls the temperature of the water flowing through the valve assembly.

Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

With reference to FIGS. 1–6, a valve assembly 10 is provided and includes a valve body 12 and a valve cap 14. The valve body 12 includes a first and

second bore

16 c, 16 h formed through a bottom portion 20, whereby the first and

second bores

16 c, 16 h enable fluid communication between the valve body 12 and a pair of water supply lines 22, 24 (as seen in FIGS. 5 and 6). In addition, a valve cartridge 26 is supported within valve body 12 to selectively control water supplied through the valve assembly 10 and discharged from an outlet port 28 formed through the valve cap 14.

The valve body 12 includes the bottom portion 20 and first and

second arms

30, 32 integrally formed therewith. As best shown in FIGS. 3 and 4, the bottom portion 20 is a generally cylindrical body having the first and

second bores

16 c, 16 h formed therethrough in a generally diametric relationship. The first and

second arms

30, 32 extend from the bottom portion, whereby each

arm

30, 32 includes an arcuate surface 34 defining a portion of a cylindrical wall extending axially upward from bottom portion 20. In this manner, the first and

second arms

30, 32 cooperate with the bottom portion 20 to define an interstitial space 36 operable to receive the valve cartridge 26, as will be discussed further below.

The valve cap 14 includes a first and second

cylindrical portion

38, 40, a central bore 42 formed therethrough, and a pair of flanges 44. The first cylindrical portion 38 is disposed adjacent the second cylindrical portion 40 and is adapted to retain a seal 46, as best shown in FIG. 1. The flanges 44 extend from the second cylindrical portion 40 and define recesses 48 therebetween. The recesses 48 are operable to receive the first and

second arms

30, 32 of the valve body 12, when the valve 10 is assembled. A pair of tabs 39 extend from the second cylindrical portion 40 in recesses 48 and engage apertures 35 formed through first and

second arms

30, 32. In this manner, the valve cap 14 may be releasably coupled to the valve body 12. The valve cartridge 26 is disposed between the second cylindrical section 40 of the valve cap 14 and the bottom portion 20 of the valve body 12 and is operable to control an amount of fluid flowing through the first and

second bores

16 c, 16 h, as will be discussed further below.

With reference to FIG. 3, a first embodiment of the valve cartridge 26 is provided and includes a first and second

rotatable disk

50, 52, a first, second, and third

stationary disk

54, 56, 58, and a first and

second disk driver

60, 62. The first and second

rotatable disks

50, 52 are generally cylindrical members and include a pair of ears 68 extending from an outer edge thereof. The first rotatable disk 50 includes first and

second bore

64 h, 66 c while the second rotatable disk 52 similarly includes a first and

second bore

64 c, 66 h. The

first bores

64 h, 64 c include a generally arcuate surface 70 disposed opposite a straight or planer surface 72, whereby the arcuate surface 70 cooperates with the straight surface 72 to form the shape of a semicircular aperture. The

second bores

66 c, 66 h are formed adjacent the

first bores

64 c, 64 h and include an arcuate surface 74 formed between a pair of straight surfaces 76, as best shown in FIG. 3. The pair of straight surfaces 76 cooperate with the arcuate surface 74 to form a generally quartercircular or triangular-shaped aperture.

The first, second, and third

stationary disks

54, 56, 58 each include a generally circular main body 78, a pair of flanges 80, and a pair of

bores

82 c, 82 h. The flanges 80 extend from the main body 78 and serve to form a pair of recesses 84 therebetween, as best shown in FIG. 3. The recesses 84 engage

arms

30, 32 to align the first, second, and third

stationary disks

54, 56, 58 with the valve body 12 and prevent rotation therebetween. Specifically, the recesses 84 receive the first and

second arms

30, 32 of the valve body 12 and serve to prevent rotation of the first, second, and third

stationary disks

54, 56, 58 relative to the valve body 12 through the engagement of the

arms

30, 32 with the flanges 80. In this manner, the recesses 84 concurrently prevent rotation of the

disks

54, 56, 58 and help align the valve cartridge 26 with the valve body 12. The

bores

82 c, 82 h are formed in a diametric relationship and generally include a quartercircular or triangular shape similar to that of the

second bores

66 c, 66 h of the first and second

rotatable disks

50, 52.

The first and

second disk drivers

60, 62 include a central bore 86 and first and

second extensions

88, 90. The central bore 86 of the first and

second disk drivers

60, 62 receive the first and second

rotatable disks

50, 52, respectively for rotation therewith. Specifically, an inner surface of bore 86 includes a pair of slots 92 formed opposite one another, whereby the slots 92 receive the ears 68 of the

rotatable disks

50, 52. In this manner, the engagement between the ears 68 and the slots 92 serves to selectively fix the

rotatable disks

50, 52 for co-rotation with the

disk drivers

60, 62. To rotate the

disk drivers

60, 62, and ultimately the

rotatable disks

50, 52, a force is applied to the first and

second extensions

88, 90 to rotate

rotatable disks

50, 52.

As previously discussed, the valve cartridge 26 is disposed between the valve cap 14 and the bottom portion 20 once assembled. To assemble the valve cartridge 26 to the valve body 12, the

rotatable disks

50, 52,

stationary disks

54, 56, 58, and

disk drivers

60, 62 are stacked in a predetermined relationship relative one another. Specifically, the first stationary disk 54 is placed adjacent the bottom portion 20 with a gasket 94 disposed therebetween. The gasket 94 effectively seals an area around the

bores

16 c, 16 h of the valve body 12 and the

bores

82 c, 82 h of the stationary disk 54, whereby the gasket 94 allows fluid flow from the bottom portion 20 to the stationary disk 54 but prevents leakage therefrom. The first stationary disk 54 is aligned with the bottom portion 20 such that the

bores

82 c, 82 h of the disk 54 align with the

bores

16 c, 16 h of the valve body 12. As previously discussed, the interaction between the recesses 84 and the

arms

30, 32 facilitates alignment of the first disk 54 with the valve body 12 and further ensures proper alignment of the

bores

82 c, 82 h with the

bores

16 c, 16 h.

Once the first stationary disk 54 is in place, the first disk driver 60 and first rotatable disk 50 are rotatably assembled to the valve body 12, whereby the first rotatable disk 50 is fixedly received by the central bore 86 of the first disk driver 60, as previously discussed. The first and

second extensions

88, 90 are assembled to the valve body 12 such that they are free to rotate between the first and

second arms

30, 32, as best shown in FIG. 1. In this regard, a range of motion is defined between the first and

second arms

30, 32, whereby a first position is established when the first extension 88 contacts the first arm 30 of the valve body 12 and a second position is established when the second extension 90 contacts the first arm 30 of the valve body 12.

Once the first disk driver 60 and first rotatable disk 50 are assembled, the second stationary disk 56 is aligned with the valve body 12. The second stationary disk 56 is assembled to the valve body 12 in the same manner as the first stationary disk 54, whereby the recesses 84 align with the first and

second arms

30, 32 to align the

bores

82 c, 82 h with the

bores

16 c, 16 h and further to prevent rotation between the second stationary disk 56 and the valve body 12. The second disk driver 62 and second rotatable disk 52 are assembled to the valve body 12 in the same manner as the fist disk driver 60 and first rotatable disk 50, whereby the first and

second extensions

second arms

30, 32. Again, a range of motion is defined between the first and

second arms

The third stationary disk 58 completes the installation of the valve cartridge 26 to the valve body 12, whereby the recesses 84 of the disk 58 are aligned with the first and

second arms

30, 32 of the valve body 12 to properly align the

bores

82 c, 82 h of the disk 56 with the

bores

16 c, 16 h of the lower portion 20. To maintain the relationship between the

rotatable disks

50, 52,

stationary disks

54, 56, 58, and

disk drivers

60, 62, the valve cap 14 fixedly engages the first and

second arms

30, 32 of the valve body 12. Specifically, the

arms

30, 32 are received by the recess 48 of the valve cap 14, whereby tabs 39 fixedly engage the apertures 35 formed in the first and

second arms

30, 32. In addition, an O-ring 95 is disposed between the valve cap 14 and the third stationary disk 56 to prevent fluid from escaping therebetween, and further to ensure that the fluid may be received through the central bore 42 of the valve cap 14.

With reference to FIGS. 5 and 6, a coupling 100 is operable to connect the valve assembly 10 within a faucet neck 110. The coupling 100 includes a valve housing 101 and a cap 103. The valve housing 101 is generally cylindrical in shape with a portion of the sidewalls removed to afford access to the valve assembly 10 and specifically the

extensions

88, 90. In this manner, valve housing 101 is similar to valve body 12. The cap 103 secures the valve body 12 within the valve housing 101. A threaded interface 107 is provided between the valve housing 101 and the cap 103. A set of external threads 105 is also provided on cap 103 to connect the coupling 100 within the faucet neck 110.

As can be appreciated from the above description, each

disk

50, 52, 54 must seal at the interface with the adjacent disk(s) to provide proper functioning of the valve cartridge. For this reason, the use of a ceramic valve disk is presently preferred. However, one skilled in the art will recognize the other types of valve disks which provide adequate sealing at the disk interface may be utilized in the present invention.

With reference to the Figures, the operation of the valve assembly 10 will be described in detail. The valve assembly 10 is operable to control the temperature of a flow of water entering the bottom portion 20 through

bores

16 c and 16 h. Specifically, the valve assembly 10 regulates the flow of hot and cold water entering the

bores

16 c and 16 h respectively to provide a desired output temperature through the bore 42 of the valve cap 14.

To control the flow of hot and cold water, the

rotatable disks

50, 52 are rotated counter-clockwise from a first position to a second position to selectively align the

bores

66 c, 66 h with the

bores

16 c, 16 h of the bottom portion 20. Specifically, to allow a flow of cold water to reach the outlet bore 42 of the valve cap 14, the first disk driver 60 is rotated generally from the first position to the second position by applying a force to the first extension 88. Rotation of the disk driver 60 causes concurrent rotation of the first rotatable disk 50, whereby sufficient rotation of the disk 50 causes the bore 66 c to align with the first bore 16 c of the bottom portion 20, thereby allowing a flow of cold water to enter the valve body 12. As the first extension 88 rotates from the first position to the second position, the flow of cold water through the bore 66 c increases to a maximum when the extension 88 reaches the second arm 32 due to the shape of the bore 66 c. Once the first extension 88 contacts the second arm 32, the first rotatable disk 50 is in the fully open position and the maximum amount of cold water is permitted to flow to the outlet bore 42. The configuration of bore 64 h allows hot water to flow through first rotatable disk 50 irrespective of its angular position.

To provide a flow of hot water to the outlet bore 42, the second disk driver 62 is rotated between the first and second positions by applying a force to the second extension 90. Rotation of the disk driver 62 causes concurrent rotation of the second rotatable disk 52, whereby sufficient rotation of the disk 52 causes the bore 66 h to align with the second bore 16 h of the bottom portion 20, thereby allowing a flow of hot water to enter the valve body 12. As the second extension 90 rotates from the first position to the second position, the flow of hot water through the bore 66 h increases to a maximum when the extension 88 reaches the second arm 32 due to the shape of the bore 66 c. Once the second extension 90 contacts the second arm 32, the second rotatable disk 52 is in the fully open position and the maximum amount of hot water is permitted to flow to the outlet bore 42. The configuration of bore 64 c allows cold water to flow through second rotatable disk 52 irrespective of its angular position.

In passing through the

bores

66 c, 66 h of the respective

rotatable disks

50, 52, the hot and cold water ultimately reach the outlet bore 42 via the

bores

64 c, 64 h formed in the first and second

rotatable disks

50, 52. Specifically, when the first rotatable disk 50 is in the first position, thereby not allowing a flow of cold water to reach the outlet bore 42, a flow of hot water is permitted to flow through the first rotatable disk 50 and reach the second rotatable disk 52 via the bore 64 h formed in the first rotatable disk 50. In this regard, a stream of hot water may be selectively adjustable when the first rotatable disk 50 is in the first position. The same relationship exists with respect to a flow of cold water. When the first rotatable disk 50 is in the second position, thereby allowing a flow of cold water to reach the outlet bore 42, and the second rotatable disk 52 is in the first position, thereby not allowing a flow of hot water to reach the outlet bore 42, the cold water will reach the outlet bore 42 via the bore 64 c of the second rotatable disk 52. In this manner, the first and second

rotatable disks

50,52, provide the valve assembly 10 with the ability to independently control the flow of hot and cold water exiting the bore 42.

In the foregoing description, it should be understood that the flow of water entering through the first and

second bores

16 c, 16 h is permitted to flow through the

bores

82 c, 82 h formed in the

stationary disks

54, 56, 58, whereby the

bores

82 c, 82 h are aligned with the

bores

16 c, 16 h of the bottom portion 20. In this regard, the

bores

82 c, 82 h provide a path for the water to pass between the

rotatable disks

50, 52 and ensure that the water reaches the outlet bore 42 of the valve cap 14.

With reference to FIG. 4, a second embodiment of the valve assembly 10 a is provided, whereby the valve assembly 10 a is operable to independently set the temperature and the flow rate of a outlet flow through the assembly 10. In view of the substantial similarity in structure and function of the components associated with the valve assembly 10 with respect to the valve assembly 10 a, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.

The valve assembly 10 a includes the same components as the valve assembly 10 except for modifications to the first and second

rotatable disks

50, 52. In this regard, a detailed description of the common components is foregone. The first rotatable disk 50 a is operable to control the flow rate at which the water is allowed to flow through the valve body 12. To accomplish adequate flow control, a first and second bore 64 c, 64 h are formed through the first rotatable disk 50 a. The first and

second bores

64 c, 64 h are formed diametrically opposed to one another and include a generally quartercircular or triangular-shaped aperture, as best shown in FIG. 4. When the extension 88 of the first driver 60 is in contact with the first arm 30, the flow is essentially restricted from passing through the first rotatable disk 50 a. As a force is applied to the extension 88, the first disk driver 60 causes rotation of the first rotatable disk 50 a. As the first extension 88 approaches the second arm 32 of the valve body 12, the

bores

64 c, 64 h begin to align with the first and

second bores

16 c, 16 h of the bottom portion 20, thereby allowing a flow of water through the first disk 50 a. Once the extension 88 contracts the second arm 32, the first rotatable disk 50 a is in the fully open position and the maximum flow of water through the first rotatable disk 50 a is achieved.

To control the temperature of the water flow, the second rotatable disk 52 a includes bores 66 c, 66 h formed adjacent each other and include a generally triangular shape, as best shown in FIG. 4. When the extension 90 is in contact with the first arm 30, cold water is permitted to flow through the first bore 66 c. As a force is applied to the extension 90, the second rotatable disk 52 a is caused to rotate, thereby allowing the second bore 66 h to align with the second bore 16 h of the bottom portion 20. When the bore 66 h aligns with the second bore 16 h of the bottom portion 20, a flow of hot water is permitted to flow through the second rotatable disk 52 a. When the extension 90 is positioned such that it is disposed generally between the first and second arms 30, 32 a mixture of hot and cold water flows through the second rotatable disk 52 a, thereby providing a generally warm stream of water exiting the outlet bore 42. Once the extension 90 contacts the second arm 32, the bore 66 c is no longer aligned with the first bore 16 c of the bottom portion 20 while the second bore 66 h is perfectly aligned with the second bore 16 h of the bottom portion 20. In this regard, when the extension 90 contacts the second arm 32, the flow of water will be at its hottest temperature. In this manner, the first and

second disks

50 a, 52 a allow for independent adjustment of both the temperature and flow rate of the water exiting the outlet bore 42.

second bores

16, 16 h is permitted to reach the first and second

rotatable disks

50 a, 52 a due to the

bores

82 c, 82 h formed in the

stationary disks

54, 56, 58 when aligned with the

bores

16 c, 16 h of the bottom portion 20. In this regard, the

bores

82 c, 82 h provide a path for the water to pass between the

rotatable disks

50 a, 52 a and ensure that the water reaches the outlet bore 42 of the valve cap 14.

With reference to FIGS. 7–8, the valve assembly 10 is shown incorporated into a faucet assembly 104. It should be understood that while the valve assembly 10 is shown assembled to the respective faucets 104, that the valve assembly 10 a could also be substituted in its place due to the fact that the overall dimensions of the valve assembly 10 are comparable to the overall dimensions of the valve assembly 10 a. Thus, the present invention provides a valve assembly that may be re-configured for a given faucet application in a simple manner. The faucet assemblies 104 each include a first and

second handle

106, 108, whereby the

handles

106, 108 are fixedly attached to the first and

second extensions

88, 90 of the first and

second disk drivers

60, 62. In this regard, applying a force to the

handles

106, 108 will essentially transmit the force to the

rotatable disks

60, 62, thereby rotating the

rotatable disks

50, 52 and control the hot/cold water flow or alternatively control the temperature and flow rate through the outlet bore 42. In addition, the outlet bore 42 is aligned with a neck 110 of the faucet 104, whereby the neck 110 of the faucet 104 is operable to transport the water flow to a predetermined location where the water exits the faucet 104 via an outlet port 112.

The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
